Resolution rule
This market will resolve according to the result of the season series between the Dallas Cowboys and Washington Commanders during the 2026-27 NFL regular season. If the Dallas Cowboys win the season series, this market will resolve to “Cowboys”. If the Washington Commanders win the season series, this market will resolve to “Commanders”. If the Dallas Cowboys and Washington Commanders tie the season series, this market will resolve to “tie”. If any scheduled game between the listed teams during the 2026-27 NFL regular season is cancelled, not completed, or otherwise does not produce an official result — including due to a shortened, truncated, or early-ended season — the season series will be determined solely using official results of completed games. If the season is cancelled, no games between the teams are completed, or the result of the season series cannot otherwise be confirmed by January 26, 2027, 11:59 PM ET, this market will resolve 50-50. The primary resolution source for this market will be information from the NFL, however a consensus of credible reporting will also be used.

Verdict hashImmutable verdict archive
This verdict is archived as a canonical JSON object with a SHA-256 content hash. The hashed payload carries the methodology version (market_trust_card_v0_2), the canary_preview label, and a fixed boundary statement; none of them can be removed without changing the digest.

- Cross-check card_row_hash against the stored full-card receipt at https://www.convexly.app/api/market-trust/v0.2/0xf135b23f583326051d947463d93b58bd13b176ca69aca615e75234ff2589be3e/verify?venue=polymarket.
Stored v0.2 cards are frozen scorecards: a re-score inserts a new row with a new card_id and records the prior receipt in previous_row_hash, and the filed calibration design binds Convexly to never mutate frozen card-time rows. The archive is a deterministic serialization of one stored row, so the same row always reproduces the same archive_sha256.
Participant and integrity screenWho shaped the price
Participant and concentration read
Signed in, this reads how concentrated Convexly's recorded flow in this market is: the share of observed notional attributable to the single largest account, how many distinct accounts appear in that record, and how much of the flow is attributable to accounts Convexly has already scored. It is an integrity-risk screen, not a manipulation accusation and not person-level identity resolution.
Those figures are computed on Convexly's recorded participant flow, which is a periodic sample of venue trades and not a complete trade record, so each one is a property of that sample rather than of the market. The figures are shown to signed-in viewers, for markets where the recorded sample was read in full.
Not claiming: wash-trading detection; sybil detection; manipulation-free market; participant concentration measured over the whole record.
Market Fitness - pre-trade diligence (experimental)
4 of 6 diagnostics have a derivable observable on this stored card; 2 are insufficient_data. An insufficient_data row means the card lacks that input, not that the check passed.
Depth and slippage at size is a Researcher feature.
The resolution-reliability, manipulation, and basis-risk reads below are open. To see the fill cost at $100 / $1k / $10k and the executability detail, upgrade to Researcher.
Depth durability
heuristic
insufficient data
At-size depth and slippage detail is a Researcher feature. Upgrade at /pricing to see fill cost at size.
Observable: Executability pillar: worse-of(top-of-book spread, modeled price impact) from the latest inspected orderbook snapshot at 2026-08-09T14:45:29.731+00:00
Caveats: derived from a single orderbook snapshot; durability across time is not yet measured on this card; descriptive diagnostic from operator-set scoring that is not calibrated; no interval exists for this value, so none is shown rather than fabricated; gated detail requires researcher
Spread and price impact
heuristic
insufficient data
At-size depth and slippage detail is a Researcher feature. Upgrade at /pricing to see fill cost at size.
Observable: Top-of-book spread (price points) and modeled price impact for a fixed notional, from the latest inspected orderbook snapshot
Caveats: spread cost over a holding period is not modeled; this is a single-snapshot read; descriptive diagnostic from operator-set scoring that is not calibrated; no interval exists for this value, so none is shown rather than fabricated; gated detail requires researcher
Time to resolution
insufficient data
insufficient data
Venue lifecycle status on the card: active. No end date is stored.
Observable: Venue-supplied market end date or close time stored on the card
Missing input: The v0.2 card schema does not store an end date or close time, so time to resolution cannot be derived from this card.
Resolution reliability
heuristic
70 / 100 (descriptive)
Resolution source and rule text are present but not independently reviewed. Resolution rule text is stored on the card.
Observable: Resolution reliability pillar: review of the resolution source (0x69c47De9D4D3Dad79590d61b9e05918E03775f24) and stored resolution rule text
Caveats: resolved-outcome dispute history is not joined on this card; the read covers resolution source and rule text only; descriptive diagnostic from operator-set scoring that is not calibrated; no interval exists for this value, so none is shown rather than fabricated
Concentration exposure
insufficient data
insufficient data
Signed in, this reads how concentrated Convexly's recorded flow in this market is: the share of observed notional attributable to the single largest account, how many distinct accounts appear in that record, and how much of the flow is attributable to accounts Convexly has already scored. It is an integrity-risk screen, not a manipulation accusation and not person-level identity resolution. Those figures are computed on Convexly's recorded participant flow, which is a periodic sample of venue trades and not a complete trade record, so each one is a property of that sample rather than of the market. The figures are shown to signed-in viewers, for markets where the recorded sample was read in full.
Observable: Participant-flow concentration from the card's integrity screen: top account flow share, unknown flow share, scored notional share
Missing input: Participant-flow concentration is not measured on this card (no scored participant rollup or no top-account flow share).
Caveats: participant figures signed in only
Basis-risk note
descriptive
structural note
This market settles as a binary event contract: it pays a fixed amount on one discrete resolution. Offsetting a continuous exposure with a binary payoff leaves residual basis risk by construction, and binary payoffs will generally fail the ASC 815 80-125% dollar-offset band used for hedge-accounting treatment, so a position that works as an economic offset can still be carried as mark-to-market P&L. This is a structural description of the contract type, not a statement about any party's exposure.
Observable: Contract payoff structure (binary event contract) and the resolution rule text stored on the card
Caveats: structural description of the contract type, not accounting or legal advice
Published deliberately as a component table with no single combined number. Read each component against the observable it derives from; an insufficient_data row means the stored card lacks that input, not that the check passed.
These diagnostics describe observable market-quality measurements for one market. They are not investment advice, not a trading instruction, not a recommendation to take or offset any exposure with this or any market, and not a statement about any person or their positions.

Live market integrity read is a Trader feature
Trader ($499/mo) unlocks an on-demand participation-concentration read on any market: HHI of wallet volume shares with a confidence interval on every estimate, plus a round-trip self-churn share, computed live from Convexly's recorded participant flow. That record is a periodic sample of venue trades, not a complete trade record, so the read describes the sample. Descriptive structure with receipts, not a manipulation call.
Boundary of the packet
This packet is market diligence, not investment advice, not a claim of absolute truth, and not proof that any trader should buy or sell. It answers whether the market price has enough substrate to cite, monitor, discount, or ignore with receipts attached.
